GLUING nnvrcn on UNITI' G wear THREADS.

' Application filed. September 11, 1922. Serial No. 587,629.

To all whom it may concern:

TENS, subject of the King 'of Norway, residing at Copenhagen, Denmark,have invented certain new and useful Improvements in Gluing Devices forUniting l/Varp Threads, of which the followingis a specification.

F or the purpose of joining old and new warp threads in textilefactories it has been proposed to stretch the old and new-warp above oneanother between beams, in such a manner that each warpfolms two partscrossing one another, and in such a manner that the crossing of the twowarps are dis-- posed one below the other between the same warp beams onwhich there is providedfon either side of the crossing points of the'warp parts, a gluing device adapted to slide at right angles tothewarps. 'On 'top of said gluing device" the warp threads are moved inpairs by means of a cam disc, the so-called heart, reciprocating betweenthe warp beams and, alternately on either side of the crossingpointsengaging simultaneously one thread of'the old warp and one thread ofthenew one and pushing them above a glue-squirting opening on the topside of the adjacent gluing device, where the point of contact betweenthe threads is moistened by an adhesive agent squeezed drop-wise outfrom the glue container.

The details ofthe manner of action and construction of this apparatusappear from my co-pending application Serial No.

411280 filed September 18, 31920 'In gluing apparatus a small pressureffpump has heretofore been used as a: glue squirting member. l The pumpmust fre quently be inspected and cleaned, as inevitably a smallportionof the glue becomes solidified in the pump, the consequence beingthat not always the same quantity of glue is pushed forward by eachpistonstroke made bythe pump. The main polnt is, however, to supplyneither too much nor too little glue during each individual'gluingoperation but, as far as possible, always eX- actly the same quantity,i. e. one drop. As

long as the gluecontainer is approximately full of glue, and as long asno solidified particl es of glue arepresent in the pump, the latter willact with sufficient accuracy, -but when the quantity of glueis reduced,for

instance after along period of operation, h P e-P. P e. a stal s new ofBe it known that I, Fmnrz ADOLF MAN.

glue forward for each piston stroke, and, as mentioned above, solidifiedglue may render the action of the pump irregular. Furthermore,according'to my co-pending application, the glue container is not absolutely air-tight, the consequence being that in the course of timesolidified particles of glue will be formed in the glue container,

and the latter must therefore quite frequently be inspected and cleaned.

Another drawback in the above mentioned apparatus is that theglue-moistened threads, which are picked up by a catching 'sion,immediately behind the catching wheel,

of a worm on which the catching wheel deposits the glue-jointed threadswhich are then, by the rotation of this worm, moved uniformly away fromthe luing apparatus. Since the glue squirting member is in the shape ofan arm which is rotatable about a horizontal axis in the glue container,and whose surface upon which-the glue is carried is larger thanthewidtlrof the arms, and thus by being swung upward towards the innerside of the cover of the gluing appara'tus, the large portion acts in asimilar manner as a shovel and lifts a certain quantity of glue up'against the said inner side, where the arm' remains stationary for amoment therebysqueezing, through a narrow opening in the said cover, onedrop of row glue" squirting opening, never more than one drop of glue issqueezed out on top of thewarp threads held in position above the saidopening. 1 In thedrawing, in which the same reference charactersindicate like parts throughout,

Figure 1 shows the gluing device in side elevation,

The gluing device consists of a boxshaped frame 1 in which there'isprovided shaft 3 supporting, outside of the frame,

aicatching wheel 4 and a bevel gear wheel 7 5behind the catching wheel.In the gluing apparatus there is also-inserted a glue container 6, fromwhich as further mentioned below a drop of glue may be pressed outthrough a narrow opening 7 in the cover 8 -Figures 2 and 3. r

of the frame, the said cover tightly clos-' ing the gluing device withthe exception of the opening 7, The cover is not shown in "In the gluecontainer 6 there is ournalled' an arm 10 pivoted on a horizontal shaft9 and adapted to be moved by means of two rods 11 and 13, interconnectedby means'of a link 12. The rod. 11 is pivoted on a shaft -14'and' rod"13 is pivoted on a shoulder 15 of rod 10. v r

Thefree end of the arm 10," which is entirely im.

mersed in glue in the vessel 6 is thereby moved upwards along a guidingsurface 23 towards the inside of the cover 8; whereby the said wideshovel-shaped'end of;the arm '10, see Figure 2; transports a'quantityofglue.
